Change Lamp

Designs On— Global Warming

By Ricardo Figueiroa

Change Lamp poetically connects the user’s wallet to his or her energy usage patterns: over time, the effect is a more holistic understanding of inputs, outputs, and long-term effects. Change Lamp has no on/off switch because it is entirely coin-operated (after four consecutive coins, the lamp will turn off). The simplicity of the concept immediately and tangibly communicates choice and consequence. It’s a new way to interact with a product, which in the end, is the liaison between the user and the larger impact on the global energy grid.
